As on September, Google AdSense publishers are now able to "opt in" to display certain types of gambling ads in some geographic locations. In the matter, Google begin sending AdSense publisher email message letting them know that they can opt into receiving ads for gambling on their website/blog(s).
"...beginning on September 27, we're expanding the inventory of Google ads eligible to show on the AdSense network to include gambling-related ads from trusted advertisers."
Google is allowing advertising of online scratch games run by state, national or Indian reservations and national or state lotteries. It also will allow the advertising of "bricks and mortar" gambling locations and fantasy sports contests.
"In response to advertiser and publisher feedback, we've expanded the types of ads available to AdSense publishers to include some gambling-related topics," said a Google spokesperson. Adding, "Publishers control whether these ads can show on their site -- if a publisher does nothing, they will not appear -- and advertisers are required to comply with our ad policies."
Unacceptable types of ads are those that promote gambling, sports betting or casino games, for gambling software or for lotteries or scratch games that are not run by national or state officials. Gambling-related tutoring, books, vouchers or promos are also unacceptable. See Google's FAQ item for advertisers for more information, including country-specific restrictions and allowances.
